I have a brand new 55PFL8007, updated with fw When playing the Xbox or using the HTPC, I experience a slight but quite noticeable judder when either Computer or Game modes are enabled. With the option turned to off, the framerate is rock solid, however the frame lag is too big to do any serious gaming. The devices are set to 1080p and 720p, and the effect is noticeable in both display modes.
